Some of these components had a practical function to protect the wearer and some served as a kind of showy function. Kabutos that were constructed in the Heian period were made in the same way as their samurai armor, small metal plates kinda like scales on a snake or dragon were made of iron and leather laced into rows. This design can be most clearly shown in the shikoro where hundreds of scales were interlaced with the leather piece. Some of the parts that go on the kabuto were the Hachi, which is a bowl-shaped dome of the helmet that covers the head from blows from the other fighter, the Tehen, a small opening at the top of the helmet that is where the plates are riveted so they don’t fall off, the Mabizashi, which is the visor in front of the helmet that protects the wearers eyes when he is fighting, the Shikoro which is the neck guard that forms a semicircle shape around the neck to protect the wearer against arrows and attacks towards the back of the head, the Tsutamono, which is a point to attach a decorative crest known as the Maedate onto the helmet that is pretty much the showy part there are various designs to choose from, and the Shinobi-no-o, a cord used to tighten the helmet around the chin so it does not fall off. Later on during the 1400s, the samurai armor and helmets were made of lamellar scales due to demand for better equipment as Japan became mixed up in constant warfare between
